L Practical methods of operation ] The polishing and final polishing operations for marble, stone, granite, etc. described below must be performed in the order stated for trimming, smoothing, jointing, polishing and final polishing. It should be considered that, despite the difference in the hardness of the different materials, both in terms of their mixture and their homogeneity, the trimming and polishing operations are identical but not the same for all the final polishing operations. We will return to this in the last section.

• TRIMMING This operation consists of making the first pass with the machine after the flooring has been laid. The granular size of the initial abrasive is determined by the surface's regularity and the method in which it has been laid: The greater the discrepancy, the larger the size of the granules. Explanation: *Paved floor: whether to standard dimensions or not and whether in marble, stone, conglomerate, cabochon or not. If the slabs are laid regularly and if the joints do not form fins greater than 1 or 2mm, use magnesia segments with a granular size of 0. SUPERMAG | Magnesia conglomerate Prismatic segments - Rep. 100
• Granule size 000 +5 Star Super If the slabs have larger fins, we recommend the use of a Bakelite crown wheel with a granular size of 16 Q in dry application (contact your supplier for information). + Floor in the form of “MACHINED” or “RUBBLE” rock The opus may be either stone or marble, the joints are usually in granito, i.e. crushed marble mixed with cement and colorant, the joints must stand proud by a few millimetres and for this reason a Bakelite rough stone block crown wheel with a granular size of 16 Q must be used. + _Granito, with or without joints For the first pass, we recommend once again the use of a Bakelite rough stone block crown wheel with a granular size of 16 Q. If this flat and well worn, with no significant bumps, use magnesia segments with a granular size of

+ SMOOTHING This operation, after trimming, consists of reducing the marks caused by the use of coarse-grained abrasives before the floor is jointed. For all types of paved floors, magnesia segments with a granular size of 1 are recommended. + JOINTING This operation, which intervenes between granular sizes 1 and 2, is essential for all paved floors, whatever the material. It consists of resealing the holes caused by air bubble sin the cement joints or in the paving: this can be done with a liquid slip, comprising a mixture of white cement and a colorant matching the colour of the paving or with quick-drying mastic (please refer to the STONIX details). STONIX Packaging: 1 KG can or box with a tube of hardener. GLUES: Ref. 201 ............ Neutral, normal viscosity Ref. 202 .. .. Neutral, normal viscosity Ref. 205L ...........

WHITE colour Ref, 206 ST .......... TRAVERTIN colour Tube of HARDENER. Mastic glue: J OLLY TIXO After this slip has dried, which takes 24 hours in a normally heated room or 15 to 30 minutes in the case of STONIX mastic. The third operation is performed, namely polishing. English

• POLISHING This is done successively with magnesia segments with a respective granular size of 2, 3 and 4 (5 Star Super to obtain a brilliant satin finish). The successive operations using these different granular sizes enable the polishing marks gradually to be reduced and eliminated to obtain a perfect finish. IMPORTANT: It would be wrong to avoid using one of these successive granular sizes to make the operation cheaper because this would not in fact be the case since by missing out, for instance, granular size 2 and going directly to 3, twice the time must be spent to obtain an identical result. Each granular size has been designed to obtain the finish required and the stipulated method of operation must be followed scrupulously. After polishing with granular size 4, it can be agreed that the polishing is perfect and that the operation is complete: you now have paving with no ridges but which still lacks the liveliness of brilliantly polished stone. FINAL POLISHING This is an operation designed to provide a lustrous finish to the polishing operation you have just completed using granular size 4. Depending on the quality of the material, you must perform operations that we have largely Simplified by creating ‘POLYECLAIR""’ final polish powders. These powders have been designed with rationalisation in mind so that you do not have to search for the relevant chemical product suitable for each material. Crystallising powder, supplied in 2 KG plastic pots. Type À For marble and light stone Type C For dark marble and granite Type D Universal We recommend that you refer to the instructions for using our POLYECLAIR product, which will provide total satisfaction and very satisfactory performance.

DETAILS OF THE FINAL POLISHING

OPERATION Your polishing machine is fitted with a felt support plate and a polishing felt of very hard quality to ensure a constantly even finish. For light marbles and stone: you simply use a felt with no other accessory after ensuring that the paving is perfectly clean and dry. This is essential for obtaining the perfect brilliance in all circumstances. Sprinkle approximately 20g of POLYECLAIR on the floor forming a circle equal to the felt's diameter. Add a few drops of water to the powder on the surface to be polished to form a paste and pass the felt support plate over this mixture. The final polishing operation must be started, and continue to be, wet by adding a few drops of water from a sponge without ever sprinkling significantly. Now, the heating created between the felt and the floor ensures a brilliant finish. Cease adding water and continue to operate the machine so that the friction causes all the residual water on the floor to evaporate. Finish the operation by washing with water using a sludge-type vacuum cleaner. 9 L Filling the tank J + Pour water into the (22-litre) tank through the hole. The water flow is regulated by the knurled knob (B) (SEE FIG. 6). + Each time, when you have finished using the machine, close the water tap. If you will not be using the machine for a certain length of time, take care to remove the tank by removing the two screws at the front, on the base of the tank and one screw situated above the motor. Clean and rinse the water inlet holes to avoid clogging. FIG. 6

10 Start-up J The machine must not be started in vertical position or when it is raised Always take care when using the machine. Adopt a comfortable and well-balanced posture. Before starting up, remove the spanners and any adjusting tools from the floor and from the machine. > EE Keep the protective guard in place all the time you are working

+ Single-phase version: - Start the machine by turning the knob to position 1. «Three-phase version: - Ensure that the supply voltage is correct. - Set the number 220 (230V) or 380 (400V) for the rectifier in the sight glass before starting using the knob. Do not leave the key in the voltage rectifier to avoid the risk of a moving it by mistake and possibly damaging the motor. + Check that the direction of rotation is correct (SECTION 6) il L Adjustable axle ] Designed to compensate for more regular wear of the segment blocks or abrasives. + __ Rear position: for rough stone blocks (maximum weight). - Obtained by untightening lever (A) and pulling lever (B) forwards (SEE FIG. 7). + Forward position: for finishing (minimum weight). - Obtained by untightening lever (A) and pushing lever (B) backwards (SEE FIG. 7).

FIG. 7 12 H Tensioning the belt (stop the motor) To change the belt or to tension it, all you have to do is release the bolts (E) fastening the motor to the chassis and turn the tensioning screw © to the right to tension or to the left to slacken the belt (SEE FIG. 8). (The tension is checked via a hatch under the chassis when the machine is disconnected from the power supply). Never tighten the belt extremely.
